Application filed June 15, 1905. Serial No. 265,470.

To all whom it may concern:

Be it known that I, JOHN G. NEwcoMB, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Collapsible HeatingDevices and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same.

This invention has reference to a device for use in heating water andother liquids at night by the aid of a lamp as the heating agent.

The invention has for its object to provide a simple device that can beadjusted for a lamp of any size for heating water or other liquidswithin a vessel supported on said device.

The object, further, is to provide a collapsible device for the uses andpurposes described that can be contained in a box of small proportions,though the device when extended for use measures quite large.

In the appended drawings, Figure 1 is a perspective view of my devicearranged for use. Fig. 2 is a smaller view of the same as viewed fromone side and partially collapsed for packing purposes. Fig. 3 is asectional view of a portion of a corner member, showing the relation ofcertain members. Fig. 4 is also a sectional view of a portion of one ofthe corner members, showing a socket and portion of a shouldered membertherein. Fig. 5 is a top view of the said corner member, showing therelation of certain folding-arms pivoted thereto. Fig. 6 is an end viewof a foldable plate and supporting-arm therefor. Fig. 7 is a perspectiveview of two portions of a folding member, showing the pivot or point ofconnection and lock therefor.

My invention comprises four corner members, preferably of angle-iron ofthe desired length, as at A. These said members together form a squarefigure connected at top and bottom by jointed members B and C,respectively, the latter being somewhat longer than the former andpivotally connected at substantially the middle, as shown at D, the saidmembers B being likewise pivoted at the middle, as at E, as shown. Oneof the sections of the members B and C is provided with an integraloverhanging lip F, whereby the joint can only be broken in onedirection-that is to say, the joint can only be thrown upward, beinglocked in the other direction by means of said lips, as will beunderstood. The members B being shorter than the members 0 causes thedevice to have a pyramidal form, though of course it may be ofrectangular form, if desired. The said members B and C are pivotallyconnected to the extremities of the corner members A in order that, asshown in Fig. 2, the entire device may be folded together in a compactform. In order to make the folding feature understood, it may be statedthat when arranged for use, as shown in Fig. 1, the device measuresabout twelve inches square at the base and has a height of abouteighteen inches, but when folded together the measurement is about fourinches square by about twenty inches long and will enter a box ofsubstantially that size. The top of each corner member A is providedwith a vertical slot, as at G, Fig. 8, within which is pivoted one endof an arm H by a pin J. At the opposite end of the said arm H anotherarm K is pivoted, whose free end is reduced in size, leaving a shoulderat L, there being a socket at M in the angle of the member A forreceiving said reduced end, as shown in Fig. 4, said socket being solocated that the arm H is held in substantially a horizontal position,as shown. As indicated in Fig. 3, the inner pivoted end of the arm H isprovided with an enlargement h, through which the pin J extends, and soarranged that the arm will lie close to the corner member Awhenlet'down,as shown in Fig. 2. I now provide a vertically-adjustable plate N forsupporting a lam this plate bein hinged at the middle, so t at it can befolded into one-half the space occupied by it when in use. At eachcorner of said plate is an arm 0, pivoted at P, to which in turn ispivoted an extension Q, adapted to enter an opening R in the cornermember, as shown, whereby the plate is supported, as shown. In orderthat this may be made possible, the joint of the arms O and Q areprovided with the overhanging lip S, corresponding to F of the members Band C described. This prevents the arms moving on their pivots when alamp is rested upon the plate I. i

It will be seen that a series of the openings R are provided in eachcorner member A, so that the plate N described can be stationed at anyheight desired to suit the size of the lamp, it being desirable to havethe top of the lamp-chimney as near the vessel to be heated ITO may bedesired to use.

as is possible in order to heat the contents as rapidly as possible. Thearms 1 Q can be easily and quickly entered into the openings R by movingthem on their pivotal connections, that movement allowing the plate alsoto be quickly removed from the device for folding. It will be noted thatin Fig. 6 the plate is being folded and also that the arms or members 0and Q are folded together and swung on their pivots, so as to liebetween the plate-halves when folded. In this way I am enabled to reducethe said plate and its fitting to a size to easily enter the boX whichcontains the main portion of the device, as described.

In the use of the bracket-supports H K a vessel of very large size maybe set upon the device, although I may not use said brackets, as the topof the arrangement may be made large enough to support any vessel thatit By using the overhanging'lips F and S described it may be seen thatthe members provided with them are not in danger of sagging and allowingthe device to collapse voluntarily. As a matter of fact I may makevarious changes in my device as I see advantageous without departingfiom the spirit of the invention. As a matter of fact the plate N may beomitted, if desired, and the lamp may be set upon the table or othersupport on which the device rests, or if the lamp is a small one someobject may be used on which to set the lamp. Thus it is seen that theuse of the plate is not an absolute necessity.

I claim 1. A foldable stand for the purposes described comprising the les, jointed members for connecting all of the egs at top and bottom toform a complete frame, saidjointed members permitting the legs to closetogether parallel with each other said members all folding in the samedirection as illustrated.

2. In a stand for the purposes described, a series of legs, jointedmembers connecting all of the legs at top and bottom as shown, a jointedfoldable arm on each leg adapted to be raised upon the leg to form asupport as described.

3. In a stand for the purposes described, a series of legs forming apyramidal frame,

ointed members connecting all the legs at top and bottom and arranged tofold upon themselves as shown to permit the legs 'to lie parallel withone another in close order and a jointed bracket pivoted at the top ofeach leg and adapted to collapse or be raised for supporting purposessubstantially as described.

4. A stand for the purposes described comprising a series of legs,jointed foldable members connecting all of the legs at top and bottom asshown and a collapsible member within and supported by the legs andadjustable for height and having collapsible supporting-arms by which toadjust said member within the legs as described there being a series ofholes in the legs for receiving the free ends of the saidsupporting-arms.
